GAS-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 550,162, dated November 19, 1895.

Y o Application iledMay 15 1895.

To @ZZ whom it may concern.-

Be itknown that I, EDWARD N. DICKER- SON, of the city, county, and State of New York, have invented anew andA useful Improvement in. Combined Gas-Governors, of which the following is a full, true, and exact description.

This invention relates to a combination of two gas-holders or gas-governors arranged to supply--for example,` to a mingling device-A twodifferent gasesnnnisome...cases of this ,Y Y,

kind-p-as'or instance, when acetylene and air are to be mingled-itis important that an excess of air shall not be delivered in case'of the failure ofA the acetylene. In order to'prevent this difficulty, Ihavecombined two governors in such away that when either one is emptied of gas the delivery of gas from'the other one is prevented.

My invention will be readily understood from the accompanying drawing, which is generally avert-ical cross-section.

A and C represent the governors, having supply-pipes D and K, provided, respectively, with governing-valves E L, and with deliveryvalves b a, connecting to pipes F and H, respectively. As ordinarily employed, the governor A is used to supply air, while the govornor C is used tosupply acetylene, the pro- Iportion of air being less than the proportion of acetylene. On this account the pipes D F `are made of less diameter than the pipes K H. As will be seen, the valve a is controlled Serial No. 549,364. (No model.)

ently controls thesupply of gas to it. The

pipesFand H may connect with any suitable mingling device.

It is evident that the mechanical construction` may bevaried, the principle of my invention being the interaction of the two govvernors. Y m ,Y n

What I claim as my invention, and desire to secure by Letters Patent, is-

l.' The combination of the two governors A" and C, the governor A connected with delivery valve a from the governor C, and the governor C connected with delivery valve b from the governor A, substantially as described.

2. The combination of the holders A and C, with valves E L and a b, the holder A governing the valve E and the valve a in the delivery/pipe of holder C, and the holder C governing the valve L and the valve o in the delivery pipe of holder A, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

E. N. DICKERSON.
